Piercing the wall of the [[pudendal canal]], it divides into two or three branches which cross the [[ischioanal fossa]], and are distributed to the muscles and integument of the [[anus|anal]] region, and send offshoots around the lower edge of the [[gluteus maximus]] to the skin of the [[buttock]]. They anastomose with the corresponding vessels of the opposite side, with the [[superior rectal artery|superior]] and [[middle rectal artery|middle rectal arteries]], and with the [[perineal artery]]. ==See also== * [[Superior rectal artery]] * [[Middle rectal artery]] * [[Inferior rectal nerve]] ==Additional images== <gallery> Image:Gray405.png|The perineum.
